This month marks the 50th anniversary of the murder of Dr. Martin Luther King. “It is also now 50 years since the publication of a famous photograph by showing the grieving widow of the fallen martyr,” notes Poynter. The photo was taken by Moneta Sleet Jr, who from 1955 until his death in 1996 worked for the Johnson Publishing Co. The following year, 1969, the image, which was distributed by the Associated Press, was awarded a Pulitzer Prize. Sleet became the first black man to win a Pulitzer.
